How to get Sound Sleep?

Have you ever thought about sleep, in whose deep ocean we sink all our sorrow, worries and difficulties for some time, and then waking up refreshed and rejuvenated, begin to tread on the walk of life with renewed energy?  Sleep is a gift of nature, we neither have to pay for it or bear any pain to receive it.  Yet many people are not able to benefit from it fully.  There is no doubt that for healthy sleep, our body and mind need to be balanced and healthy, and our daily routine has to be well organised.  Whoever abandons a simple lifestyle and adopts a complicated and unnatural lifestyle has to suffer from sleeplessness naturally.
